Question

Q.2. In the given figure, find the value of y.
​

Answer 1

Step-by-step explanation:

2y +y = 180

3y=180

y=180/3

y= 60

Answer 2

Y = 30°

Explanation :

• Note :

The Non-Y Angle Is 90°

• Equation :

$2y + y + 90 = 180 \\ 3y = 180 - 90 \\ 3y = 90 \\ y = \frac{90}{3} = 30$

• Verification :

Sum Of The Angles In A ∆ Is 180°

30 + (30 × 2) + 90 = 180°
